Base64 or embed images inline

I have a blog site which is secure and password protected.

I wish to send a newsletter from it, but the images within the newsletter must be embedded within the email.

Important:
1) If i use the newsletter plugin as-is, the links to the images are broken in email clients, as the challenge/response is not supported in an email client.
2) I cannot move them to a CDN, or secondary static site, as the images should not be left in an unsecured state either.
3) We have previously assembled newsletters in outlook, and sent it within our group, but we are trying to uplevel the simple newsletter into a blog that emits a newsletter.

Possible solutions?
1) Newsletter plugin needs to embed and include images as it hands it off to the smtp process.
2) Newsletter needs to have a feature to add the images in as base64, where tinymce doesnt completely crash out. I was able to make newsletter plugin convert to base 64 on the fly with some quick PHP code, but it broke tinymce.

Any advice and thoughts would be helpful, perhaps there is some functionality i have missed?

Thank you!
